Please consider a use case that is described in the Emacs manual:
In order to store a window configuration on disk and
read it back in another Emacs session ...
In such use cases, I want to restore the exact same text in all buffers,
and then restore the window configuration, including display starts.
In fact, the snippet illustrates an even simpler situation: It stores
the configuration in a variable, and the session keeps running. I would
like to obtain the configuration, then close all buffers, and later
restore their contents (for example, from files), and then use
set-window-configuration to restore the original window configuration,
including all window-starts.
Could set-window-configuration be generalized to reliably restore the
window-starts also in such cases? If not, please consider adjusting the
documentation to make clear what this actually guarantees. In
particular, when are window-starts reliably restored, and when not?
Thank you and all the best,
Markus
